Title: Optical disk apparatus
Inventor: TAMURA TAIJI
IPC: G11B7/09
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of changing over an offset correction value even when a gain setting value is changed over by a method wherein an offset adjusting signal is set in such a way that the offset amount of the output of an error-signal generation part, at the time when the gain of an amplifier is set at a first gain, is made identical to the offset amount of the output of the error-signal generation part, at the time when the gain of the amplifier is set at a second gain. SOLUTION: A servo block control circuit 140 outputs a first offset correction signal 170 to an error-signal-generation-part control circuit 350 on the basis of an offset monitoring signal 190. The error-signal-generation-part control circuit 350 outputs offset correction values 360, 361 to offset adjusting circuits 310, 311. First, gains of gain changeover circuits 320, 322 are set at a maximum value, and monitoring signals 380, 381 are monitored. Then, the gains of the gain changeover circuits are set at a minimum value, and the monitoring signals are monitored. At this time, a value which is obtained at the time when the difference between a monitored value at the maximum gain and a monitored value at the minimum value is divided by a gain difference is used as an offset value to be corrected.

Title: Monitoring device
Inventor: FUJII TAKUYA
IPC: G08B13/196
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To detect the movement of an intruder from a 1st area to a 2nd area set up in a monitoring area by outputting an intruder detection signal when luminance is changed in a 1st area in a monitoring image and luminance is changed in a 2nd area in a succeeding monitoring image inputted after the lapse of prescribed time. SOLUTION: The monitoring device is provided with an intruder detection circuit 3 for detecting the intrusion of an intruder into a monitoring area based on images picked up by a video camera 1. A Y/C separation circuit 11 in the circuit 3 extracts only a luminance signal (Y signal) from a video signal outputted from the video camera 1. When a change in the luminance value of a 1st monitoring point in a monitoring field is discriminated and a change in the luminance value of a 2nd monitoring point in a succeeding monitoring field is discriminated, an image change sensing signal is outputted. Consequently many intruders can be recorded in a video tape.

Filed: 1994-03-31
Abstract: PURPOSE:To control plural printers and to improve the print job efficiency by reporting a specific printer that outputted print job to the job requester user when the print job is completed. CONSTITUTION:Plural print jobs are dynamically allotted to the printers that are controlled by the print server software and carried out them. The print server software periodically confirms the states of printers 108 and therefore gives a message to a user to tell that the printers are busy if so when the print jobs are received. Meanwhile the print jobs are automatically given to the available printers 108 if the print jobs cannot be carried out by some reasons such as the faults of printers, the shortage of print forms, the uncancelable cases of busy states due to concentration of print jobs, etc. Then the names of the printers that outputted the jobs are reported in messages. Thus the print Jobs can be effectively carried out.

IPC: B23H7/26
Filed: 1988-04-07
Abstract: The rotary drive device for the sleeve or the work holder of an erosion machine has two electric motors (8a, 8b) which each drive, for example, the sleeve (2) in a rotary movement via a transmission (6a, 6b) and gears (5a, 5b, 7a, 7b, 4). So that any backlash in the transmission and the gears is neutralised and the elasticity of the drive line is compensated, the two electric motors always run in different directions or at different rates. The entire drive line is thus always under a certain preloading, which permits accurate positioning with simple and inexpensive drive elements. <IMAGE>
